Lions coach Jim Caldwell offered no updates Monday on the statuses of quarterback Matthew Stafford, tight end Brandon Pettigrew and cornerback Darius Slay, who all sustained injuries during Sunday's season opener at San Diego.

"You'll see on the injury report on Wednesday," Caldwell told reporters, per The Detroit News.

Stafford got dinged up on a blind-side blitz midway through the third quarter Sunday, per MLive.com. He finished the game with a sleeve on his right (throwing) arm and showed up for his postgame press conference with scraping on his left arm. The Lions backup quarterback is Dan Orlovsky.

"You saw him get hit, obviously," Caldwell said after Sunday's game. "Once he got hit, it was just a way of keeping him going."

Pettigrew (undisclosed) was injured on the extra-point try on Detroit's final touchdown, while Slay did not finish the game due to an ankle injury suffered in the fourth quarter. Both players will undergo further medical testing.
